stlink-gdb-server and Nucleo-H73SL8

Uwe Bonnes · ‎2024-04-28

While "ST-LINK_gdbserver -d -v --frequency 1000 -cp ..." connects fine to STM32U083C-DK, NUCLEO-H7SL8 does not work.

Starting server with the following options:
Persistent Mode : Disabled
Logging Level : 31
Listen Port Number : 61234
Status Refresh Delay : 15s
Verbose Mode : Enabled
SWD Debug : Enabled

COM frequency = 1000 kHz
Target connection mode: Default
Target connection failed. Try connecting under reset
Target connection failed
Target unknown error 32

Error in initializing ST-LINK device.
Reason: Unknown. Please check power and cabling to target.

I lowered the frequency even much lower so frequency should be no problem. StCubeProgrammer connects fine. Stlink firmware is from stsw-link007-v3-15-6.zip

Has anybody success with this combination? Any hints?

Hello @Uwe Bonnes,

I got the same issue by running your command, then I added the -m option and it is connecting. I loaded a GPIO toggle project into the flash and I can see it is running.

Try the following command and let me know if it is working:

>ST-LINK_gdbserver --swd  -cp "C:\ST\STM32CubeIDE_1.15.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.1.200.202311302303\tools\bin" -m 1

Output is:
